Application filed June l, 1905. Serial No. 263,272.

To alt whom zit may concern,.-

Be it known that I, NAPOLEON DELIsLE, a subject of the King of GreatBritain, residing at St. Tite, county of Champlain, in the Province ofQuebec, Canada, have invented certain new and useful Improvements inWrenches; and I do hereby declare that the following is a full, clear,andexact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in wrenches;` andit consists particularly in certain means, hereinafter pointed out,whereby means are provided for securing to a rotatable shank which isfixed in position different sizes of nut-sockets, and also comprisesextension means whereby the device is especially adapted to manipulatenuts or bolts which are below the plane of the handle of the wrench; andit consists in cery tain features of novelty in the detail constructionand arrangement thereof, whereby a simple, convenient, and economicaltool is provided for the purpose described.

Referring to the accompanying drawings, in which similar numerals ofreference indicate similar parts in all the views, Figure 1 is a sideelevational view of the wrench with a nut-socket removed. Fig. 2 is alongitudinal vertical sectional view taken approximately on line 2 2 ofFig. 3. Fig. 3 is a horizontal sectional view taken on line 3 3 of Fig.2. Fig. 4 is a view showing, partly in vertical section and partly infull lines, the wrench equipped with the extension device hereinafterdescribed; and Fig. 5 is an end view of the wrench with the extensionshown in Fig. 4.

Referring to the parts, 1 is a shank which terminates at its forward endin a bifurcated head portion including the bifurcations 3 and 4, thesemembers having coaxial openings through which are projected therelatively circular stem 5, upon which is mounted the ratchet-wheel 6,said ratchet-Wheel being secured to the stem 5 by means of the pin 7passing therethrough. The stem 5 terminates at its lower end in therecess 8, the wall of said recessed portion being cut away at 9, asshown in Fig. 2.

Secured to the recessed portion of the stem 5 in convenient proximity tothe opening 9 is a spring 10, which is secured by means of the screw orpin 11, there being an outwardlycurved lip 12 on the lower end of saidspring It is understood that the nut-socket 14 has non-circular innerfaces, which may be square or hexagonal, as may be desired, to coperatewith nuts of any desired shape.

Coperating with the ratchet-wheel 6 are pawls 15, which are of springmetal and are secured, by means of the screws or pins 16, to the shank1, there being laterally-projecting lugs 17 formed on said pawls toserve as thumb-pieces for swinging said pawls upon their pivots eitherupwardly to the recess 18, relatively above the ratchet-wheel, or intoengagement with said ratchet-wheel, as may be desired.

Cooperating with the shank 5 and adapted to be connected therewith inplace of the nutsocket 14 is a removable extension-piece 19, whichextension-piece has a longitudinal opening therein, which opening is ofnon-circular form, it being understood that the extending end of thestem 5 is also of non-circular exterior.

An opening 20 is provided in one of the walls of the extension 19, saidopening 20 having a straight side 21, which is adapted to coperate withthe lip 12 to secure said extension 19 in position upon the stem 5. Anon-circular stem 22 is held in the extension by means of the set-screw23, which projects through the extension 19 into a channel 24, formed inone face of the stem 22, and it is evident that the stem 22 may projectto a greater or less distance beyond the extension 19 within the limitsof said channel by loosening the set-screw 23 and may be secured inposition when said set-screw is set home to bear against the bottom ofsaid channel 24. The stem 22 is provided with a non-circular end portion25, having one of its walls cut away at 26, there being a flat spring 27secured to the outer end of said stem 22 in convenient proximity to theopening provided at 26, and a lip 28 is formed on said spring 27, as onthe spring 10, which lip is adapted to coperate with nut-sockets 14,which may be secured to the stem 22 by means of said spring 28, as shownin Figs. 4 and 5. The nut-sockets 14a, like the nut-sockets 14 may IOObe of any crosssectional area or internal shape to adapt them to beapplied to nuts of diHerent shapes.

To prevent undue torsional strain upon the pin 7, the stem 5 is recessedlongitudinally. Resting in such recess is an inwardly-pro] ecting stud6a, Jformed integral With said ratchet, Which stud receives much of thestrain incident to the operation of the Wrench. The screws 16, Whichsecure the paWls l5 to the shank, are set into corres ondinglyscrewthreaded recesses in the bo t 16a.

Having described my invention, What I claim, and desire to secure byLetters Patent, is

1. In a Wrench, a shank terminating in a bifurcated head portion, arotatable stem mounted in perforations in said head, there being arecess in one end of said stem, aspringcatch secured adjacent saidrecess, a ratchet- Wheel on said stem Within said bifurcated head, paWlsadapted to engage said ratchet, a removable extension having anon-circular opening longitudinally thereof, a slidable non-circularstem secured therein, a spring catch on said non-circular stem, and anutsocket adapted to interlock With said catch.

2. In a Wrench, a shank terminating in a bifurcated head portion, arotatable stem mounted in perforations in said head, there being arecess in one end of said stem, a spring-catch secured adjacent saidrecess, a ratchet-Wheel on said stem Within said bifur cated head, paWlsadapted to engage said ratchet, a removable extension having anoncircular opening longitudinally thereof, a slidable non-circular stemsecured therein,

there being a channel in said stem, a set.

screW in said extension adapted to bear in said channel, a spring-catchon said non-circular stem, and a removable nut-socket adapted tointerlock with said catch.

In Witness whereof I have hereunto set my hand in the presence ,of tWoWitnesses.
